Discussion:

Section 20.2.9 [allocator.traits] says: 

static size_type max_size(const Alloc& a) noexcept;

Section 20.2.9.3 [allocator.traits.members] says: 

static size_type max_size(Alloc& a) noexcept;

These should be the same.

Discussion:

Pablo (who I believe wrote the allocator_traits proposal) says "The function should take a const reference."

No objections, so moved to Immediate.

Proposed resolution:

This wording is relative to N3691.

  1. Change 20.2.9.3 [allocator.traits.members] as follows:

    static size_type max_size(const Alloc& a) noexcept;
